SHOE-SOLE-CEMENTING- APPARATUS.

Application filed February 21, 1927. Serial No. 169,699.

This invention relates to the shoe constructing and repairing art, and more particularly to an appliance for use in cementing soles or heels to the bottoms of shoes.

The invention has for its principal objects to provide an appliance capable of cooperation with a shoe last and last jack when these two elements are used in their proper relation in a shoe factory repairing establishment or the like. Another object is to provide a structure whereby an elastic means may be held in tightly stretched position over the sole of a shoe as the shoe is mounted on a last. A further object is to provide a structure or appliance for use in connection with a last of conventional type and which may be removed therewith from a jack, and which is also capable of detachment from the last.

In its broadest embodiment, the invention comprises an open frame for relative cooperative movement with a shoe last, and when in operative position with the shoe bottom uppermost to lie beneath the sole portion and the last, and to maintain stretched or under tension an elastic member or members disposed transversely of the shoe sole in contact therewith; means being provided for releasably holding the frame in its operative position, and if desirable, but not essential, means may be provided for detachably connecting the frame with the shoe last.

With the above mentioned and other objects in View, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, andset forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the'claims may be resorted to without departing from the spirit or sacrificlng any of the advantages of the invention.

To more clearly comprehend the invention, reference is directed to the accompanying drawings, wherein Fig. 1 is a view in side elevation of the preferred embodiment of the invention in operative position, holding a sole to the bottom of a shoe.

Fig. 2 is a transverse sectional view on line 22 of Fig. 1 illustrating particularly the a conventional shoe jack provided with a tapered upper end 2, a base 2, and a swivel connection between the members 1 and 2. Detachably positioned on the tapered upper end 2 of the jack 1 is a conventional shoe last 3 over which there is adapted to be positioned in a conventional manner, a shoe 4: to be repaired. the latter being illustrated in dotted lines Fig. 1.

5 is an open frame the configuration corresponding somewhat to the outline in plan of the sole portion of the last 3, and also curved to correspond somewhat to the curvature of the sole portion of the last 3,-as viewed in side elevation, the frame, however, being of a size to readily receive the last 3 as clearly illustrated in Figs. 2 and 3 of the drawings. As illustrated in the preferred embodiment, one end of the frame is preferably fulcrumed at 6 to the upstanding portion 7 of the plate 8 disposed horizontally beneath the last 3, and which plate is provided with an aperture 9 through which is adapted to extend the portion 2 of the jack 1 when the plate is mounted thereon. The plate at its forward edge is illustrated as mounting a pivoted latch 10, the recesses 11 of which are adapted for receiving the free end of theframe and preclude the same from moving upwardly relatively to the last 3 until released.

The plate 8 may be permanently or detachably united to the last 3 in any suitable man nor, the structure illustrated affording a detachable connection between the plate and last, and the same is constructed in the following manner On each side of the opening 12 in the last 3 for receiving the mounting end 2 of the jack 1, the last is provided with the parallel spaced recesses 13 formed with the off-set flanges 14. The hooked ends 15 of member 16 extending iii? in parallel spaced relation upwardly from the upper surface of the plate 8 have hooked ongagement with flanges 1 1. It will be observed that the last 3 is provided with offset flanges 14 for engagement by the hooked ends 15 of the member 16 when the plate and last are assembled. It will also be observed that when the plate and last are positioned as illustrated on the upper end of the jack that the end of the jack passing through the aperture 9 on the plate and the opening 12 in the last holds the last and plate in their relative positions, as illustrated in Fig. 1. The last and plate may only be detached and. separated from each other at such time as both are removed from the jack.

A tubular elastic member 17 consisting of several sections or one single section is adapted for endwise movement inwardly of the frame 5 from its free end to be disposed transversely of the upper surface of the sole portion and the (last 3.

With the plate 8 mounted as in the drawings and the last 3 positioned on the jack 1, as illustrated, and the shoe to be repaired positioned on the last 3 with the adhesively coated sole in position on the shoe bottom, the frame 5 which has previously been swung on its fulcrum backwardly and hangs in a downward or vertical position, is now swung upwardly, the elastic member 17 either in one piece or of sectional construction is positioned endwise over the frame 5 and the frame is swung downwardly with the side rails 18 thereof lying below the upper surface of the foot portion of the last 3. This action stretches the elastic member 17 transversely of the sole 19, which is being applied, and the engagement of the hook 10 at the end of the frame 5 retains the frame in the desired position until such time as the adhesive has dried or set. Immediately after the engagement of the latch 10 with the free end of frame the last with the shoe mounted thereon and the plate 10 may be removed as a unit from the jack 1, and placed aside until such time as the attachment of the sole to the shoe bottom has been completed. This leaves the jack free for other uses, and should it be desired, after the sole has set to the shoe bottom and the plate 8 with its frame 5 may be detached from the last 8 and the last used independently thereof for other work in connection with the ack 1.

I claim 1. In combination with a last jack, a shoe last fordetachable association therewith, a pivotally mounted open frame also detachably associated with the jack and removable therefrom with the last, said frame adapted for operative movement downwardly over the jack, elastic means acted on bythe frame for stretching over the last on the downward movement of the frame, and means for releasably retaining the frame in its operative position.

2. In combination with a shoe last, an open frame operatively movable over the last, elastic means acted on by the frame for stretching over the last on the operative movement of the frame thereover, means for releasably holding the frame in its operative position, and means for detachably associating the frame and last.
